Abstract

The internal combustion engine includes an engine block 30 having at least one cylinder 14, a piston 46 mounted within the cylinder 14 for reciprocal movement in the cylinder, a fuel injector 62 for injecting fuel into the cylinder 14 and circuit means 70 for generating an injection control signal indicative of a fuel injection event and for generating a spark in the cylinder a predetermined amount after generation of the injection control signal. The engine is operated with time-based ignition when all of one or more engine conditions are in respective given ranges and is operated with crank-angle-based ignition when any one of the engine conditions is not in a respective given range.
